types of filler wire for gas welding

admin

hi i was wondering if any one can tell me the types of filler wire used in gas welding
Reply:On steel the typical filler for gas welding is RG45 or RG60. I have used ER70S2 and ER70S6 also.It seems to work as well as the RG45.I have done some stainlees with 308 filler and Solarflux. Got good penetration but it was definitely what you would call UGLY.mm135HTP Invertig 201 With water cooler9" Southbend LatheLots of hand tools.

Reply:Good list. I say got to home depot and get a 1# roll of er-70 mig wire in the bigest you can find probably .045 bigger is better to a point say 1/16". After you get the roll cut it onto 3' lenghts and straiten them out a little and your ready. when I use mig wire I put it in a vice and put vice grips on the other end and pull and twist about a half turn. Mig wire cost a lot less and works just as good. Steel Thunder Welding LLC.

Reply:There is also brass rod for brazing the comes with or without flux coating.For the non flux coated wire you can get flux in a can that you dip the wire into,Also there are nickel silver rod or wire that has a blue flux coating,You can braze thin stainless tubing with the nickel silver.Trying to use mig copper coated wire will work, but trying to handle the small wire and keep it from twisting or coiling up is probably no fun. Probably hard on the hands.I have seen it used overseas in bicycycle frame sweatshops.

Reply:I understand the inclusion aspect with using er wire but the things I O/A are never critical and I doubt most people who use O/A are not using it for critical welds. I use O/A often and make welds that are nearly as nice at with my TIG just a huge HAZ. I usualy use my 1/16" mild steel TIG rods or mig wire. I even used the process to weld the entire frame for my utility body on my truck. (2'X2"thin wall square tubing from HD) Steel Thunder Welding LLC.
